This study describes a heat transfer characteristic of pulsating airflow around an obstruction mounted in a rectangular duct. Several researchers have reported the possibility of the heat transfer enhancement by pulsating flow. Our study is trying to apply pulsating flow to the heat transfer enhancement method in electronic equipment. In this report, the heat transfer performance of the pulsating airflow around the cylinder type obstruction while changing the diameter of the obstruction. The obstructions simulate components in electronic equipment. It is found that heat transfer around the obstruction can be enhanced by the flow pulsation regardless of the dimension of the obstruction.
